This recently described (2004) new species from Central Kalimantan (Indonesia)
resembles strongly the today well known Cryptocoryne pygmaea from the Philippines. The leaves are however bright green and there are some (small)
differences in the spathe. But the chromosome
number is different, C.ideii has 2n = 20 while C. pygmaea has 2n=
34. See the full description at the Document Service.

Cryptocoryne ideii is known from just one locality where it grows together
with C. fusca. There are strong indications that a
few other collections from Kalimantan, quite distant from the type locality, may refer to
the this species.
C. ideii is rather easy to grow and it may be a good aquarium plant.
